The granny square remains a foundational project for anyone picking up a hook because it teaches rhythm, tension, and construction in a single portable module. Mastering this motif opens the door to heirloom blankets, modern garments, and quick stash-busting accessories.
What Is a Granny Square
A granny square is a crochet motif worked in the round from the center outward. The classic version uses clusters of three double crochet stitches separated by chain spaces to create an open, lacy fabric that grows geometrically with each round. While the name suggests a single style, the term now covers countless variations including solid squares, hexagons, and triangles. The version taught here is the traditional openwork square that has appeared in pattern books since the early nineteenth century. Its popularity surged in the 1970s and continues today because the repeating pattern is easy to memorize and the modules join together without sewing seams.
What You’ll Need
Gather a few basic supplies before you begin. Having everything within reach keeps the learning process smooth.
- Yarn: A smooth, light-colored worsted weight (Category 4) yarn makes stitch definition easy to see. Acrylic, cotton, or wool blends all work well.
- Hook: A 5.0 mm (US H-8) hook is standard for worsted weight. Adjust up or down if your tension runs tight or loose.
- Scissors: Sharp snips for clean cut ends.
- Tapestry needle: For weaving in tails after the square is complete.
- Stitch markers: Optional but helpful for marking the first stitch of each round.

Stitches You’ll Use
The classic granny square relies on only three techniques. Practice each one on a small swatch before starting the square.
- Chain (ch): Yarn over and pull through the loop on the hook. This creates the foundation ring and the corner spaces.
- Slip stitch (sl st): Insert hook into indicated stitch, yarn over, pull through both the stitch and the loop on the hook. Used to join rounds and move the hook position.
- Double crochet (dc): Yarn over, insert hook into stitch or space, yarn over, pull up a loop (three loops on hook), yarn over, pull through two loops, yarn over, pull through remaining two loops. The granny square is built from clusters of three double crochets.
For a visual refresher on these stitches, see our illustrated stitch dictionary.
Step-by-Step: The Classic Granny Square
The instructions below use US terminology. Each round begins with a chain that counts as the first double crochet unless noted otherwise. Work all stitches into the chain spaces rather than the top of stitches from the previous round; this creates the signature open look.
Starting: The Magic Ring
The magic ring (also called magic circle or adjustable loop) creates a tight center with no hole. Hold the tail end of the yarn in your non-dominant hand. Wrap the working yarn around two fingers to form a loop crossing over the top. Insert the hook under the first strand, grab the second strand, and pull up a loop. Chain three (counts as first dc). You will work the first round into this loop. When the round is complete, pull the tail to cinch the center closed. If the magic ring feels awkward, chain four and slip stitch into the first chain to form a ring; work Round 1 into that ring.
Round 1: The Center
Into the ring: *3 dc, ch 3. Repeat from * two more times. You now have three clusters and three corner spaces. Join with a slip stitch to the top of the beginning chain-3. Pull the tail to close the center. You should have four clusters of 3 dc separated by four ch-3 corner spaces.
Round 2: Building Out
Slip stitch into the next two stitches and into the first corner space to position the hook. Chain 3 (counts as dc). In the same corner space work 2 dc, ch 3, 3 dc. This forms the first corner of Round 2. *In the next corner space work 3 dc, ch 3, 3 dc. Repeat from * two more times. Join with a slip stitch to the top of the beginning chain-3. You now have four corners each with two clusters separated by a ch-3 space, and no side clusters yet.
Round 3: The Pattern Emerges
Slip stitch into the next two stitches and into the corner space. Chain 3. In the same corner space work 2 dc, ch 3, 3 dc. *In the next ch-3 space (the side space) work 3 dc. In the next corner space work 3 dc, ch 3, 3 dc. Repeat from * two more times. In the final side space work 3 dc. Join with a slip stitch. The square now has a cluster on each side between the corners.
Round 4 and Beyond
The established repeat is simple: every round starts in a corner with chain-3, 2 dc, ch 3, 3 dc. Each side space receives one cluster of 3 dc. Each corner receives two clusters of 3 dc separated by ch 3. Continue adding rounds until the square reaches your desired size. A typical blanket square finishes at 6 to 8 inches, which is usually five to seven rounds with worsted weight and a 5.0 mm hook. Fasten off and weave in all ends with a tapestry needle.
Common Troubleshooting
- Square curls upward: Tension is too tight. Go up a hook size or consciously relax your grip.
- Square ruffles at the edges: Tension is too loose or you are adding extra stitches. Count clusters each round; each side should gain exactly one cluster per round.
- Center hole remains open: Pull the magic ring tail firmly after Round 1 and again after Round 2. Secure the tail by weaving it through the center stitches in multiple directions.
- Corners look pointed instead of square: Ensure you are working the ch-3 corner space every round. Skipping the chain space narrows the corner angle.
Joining and Project Ideas
Once you have a stack of squares, you can join them with a whip stitch, slip stitch, or join-as-you-go method for a seamless finish. The join-as-you-go technique connects the final round of a new square to the adjacent square as you work, eliminating a separate seaming step. For a detailed walkthrough of that method, read our join-as-you-go tutorial.
Project possibilities scale with your ambition. Four squares make a coaster set. Nine squares form a cushion cover. Twenty-five squares create a baby blanket. One hundred squares yield a generous throw. Mix solid and variegated yarns for a scrappy look, or plan a color gradient for a modern ombre effect.

Next Steps for Growing Crocheters
After the classic square feels automatic, explore variations. The solid granny square replaces chain spaces with double crochets for a denser fabric ideal for garments. The sunburst granny adds color changes every round for a starburst center. Hexagons and triangles expand your geometric toolkit for modular designs. Each variation builds on the same muscle memory you developed here.
Keep a small project bag with a hook and a skein of yarn by your favorite chair. A few rounds each evening accumulate quickly. Before long you will have a stack of squares ready for whatever project inspires you next.
